Curtiss-Wright’s Defense Solutions division, a trusted leading supplier of rugged data storage and protection solutions, announced today that it has received Common Criteria (CC) certification for both the hardware and software disk encryption layers integrated in its Data Transport System (DTS1) Network Attached Storage (NAS) device. The DTS1 is the embedded industry’s first commercial off-the-shelf (COTS) data-at-rest (DAR) storage solution designed to advocate two layers of complete disk encryption (FDE) in a sole device. In the United States, the National Information Assurance Partnership (NIAP) validates COTS information technology (IT) products to ensure they conform to the international Common Criteria Evaluation and Validation Scheme (CCEVS), which is recognized around the world by 17 Certificate Producing countries and by 11 Certificate Consuming countries. Having received certification, the hardware and software FDE layers used in the DTS1 are now currently listed on the United States NIAP Product Compliant List.

Curtiss-Wright has too obtained National Security Agency (NSA) (nsa.gov) approval for utilize of the two CC-certified FDE layers as Commercial Solutions for Classified (CSfC) components. As a result, the two DTS1 encryption layers are now listed on the NSA’s CSfC Components List and can live proposed as a DAR solution. Selecting a pre-approved device from the CSfC Components List enables system architects to greatly reduce the time and cost needed to design a COTS encryption solution, enabling them to start system development immediately, while too greatly reducing their program risk.

“We are very arrogant to broadcast that their DTS1 Data Transport System Network Attached Storage solution, the industry’s first rugged network attached storage device to advocate two layers of encryption as described in NSA's Data-at-Rest Capability Package, has successfully received NIAP Common Criteria certification and NSA CSfC approval,” said Lynn Bamford, Senior Vice President and common Manager, Defense Solutions division. “Use of the DTS1, with its certified software and hardware encryption layers, eases and speeds the aptitude of system designers to protect Top stealthy data with an NSA-approved cost-effective alternative to nature 1 encryption.”

The DTS1 uses CSfC two-layer encryption, an NSA-approved approach for protecting classified National Security Systems (NSS) information in aerospace and defense applications. By incorporating a two-layer encrypted CSfC solution, which uses cost-effective commercial encryption technologies in a layered solution, system integrators can significantly reduce the cost and time to develop and deploy secure DAR solutions. The NSA established the CSfC program as an alternative approach to nature 1 encryption in order to accelerate the protection of Top stealthy data. The rugged wee form-factor DTS1 is designed to store and protect great amounts of data on helicopters, unmanned aerial vehicles (UAV), unmanned underwater vehicles (UUV), unmanned ground vehicles (UGV), and Intelligence Surveillance Reconnaissance (ISR) aircraft that require the protection of sensitive DAR.

The NIAP evaluation process (niap-ccevs.org) is structured to meet CCEVS and is conducted by a Common Criteria Testing Laboratory (CCTL) accredited under the National deliberate Laboratory Accreditation Program (NVLAP). The DTS1 NAS system was evaluated by Gossamer Security Solutions, one of the nation’s leading evaluation and testing laboratories approved to conduct testing and evaluation for both CC and FIPS 140-2 encryption.

About the DTS1 2-Layer Encryption ApproachThe DTS1 uniquely incorporates two distinct layers of Commercial National Security Algorithm (CNSA) Suite cryptographic encryption into one device, making protection of Top stealthy data more cost efficient and low risk. The DTS1’s two-layer data encryption process followed the NSA’s Data At repose Capability Package as a design template and is based on the hardware and software FDE solution approach. Both the hardware and software FDE layers luxuriate in been individually evaluated and certified against two CC protection profiles: (1) collaborative Protection Profile for complete Disk Encryption Encryption Engine; (2) collaborative Protection Profile for complete Disk Encryption Authorization Acquisition.

About Common CriteriaCommon Criteria is a technically demanding international set of guidelines for security certification that is required by the U.S. and 27 national governments worldwide for departments and agencies seeking to procure commercial products. Common Criteria certification provides assurance that the process of specification, implementation and evaluation of technology products has been conducted in a rigorous, standard, and repeatable manner.

About the DTS1The very wee DTS1 NAS device, which weighs only 3.77 lb. (1.71 kg) and measures only 1.5 x 5.0 x 6.5” (38.1 x 127 x 165.1 mm), delivers up to 4 TB of solid state storage (SSD) with two layers of certified encryption. It supports PXE protocol so that network clients on a vehicle or aircraft can quickly boot from the encrypted files on the DTS1’s removable reminiscence cartridge (RMC). This approach both facilitates software updates for network clients and significantly reduces SWaP by eliminating the necessity for individual arduous disks in each network client. Curtiss-Wright offers 2-Layers of encryption in two mounting options of the DTS1, the VS-DTS1SL-FD, which is designed for cockpit utilize with DZUS mounting panel, and the VSDTS1SL-F, which uses L-brackets to advocate very elastic mounting within space-constrained platforms.

Three of the ample headlines so far this year luxuriate in been data growth, the economy and data deduplication in backup. The first headline, relentless data growth, is the root antecedent of most issues in the backup environment. In an endeavor to meet service-level agreements (SLAs) for data backup and recovery, more and more organizations are deploying disk in the backup process. With disk, IT organizations can better meet backup windows and recovery objectives. But as IT "modernizes" its backup infrastructure with disk-to-disk backup, novel problems emerge -- specifically, the cost of managing copies stored on disk, and the feasibility of taking disk-based backup copies and making them portable for offsite and/or long-term storage.

Deduplication addresses the first issue -- it changes the economics of disk-based backup, allowing more data to live stored in a smaller footprint. The second problem is the novel throe point for discontinuance users that luxuriate in adopted disk. How can they rapidly, securely, cost-effectively, and efficiently come by data offsite for catastrophe recovery (DR) or long-term retention? Sure, most target devices with deduplication can replicate copies, but is the backup application's catalog vigilant of the copy? That's where Symantec Corp. Veritas NetBackup OpenStorage (OST) technology comes in.

Symantec announced its NetBackup OpenStorage initiative a few years ago. It is designed to allow NetBackup users to utilize third-party storage solutions without the necessity for tape emulation.

Available as an option for NetBackup 6.5 and higher, NetBackup OpenStorage gives NetBackup a common interface for third-party disk targets. NetBackup sees OST-enabled appliances as disk, enabling features such as smart capacity management, media server load balancing, reporting, and lifecycle policies. It too delivers optimized duplication. Without OST, NetBackup media servers luxuriate in to manage totality duplicate backup copies, which means that data must live transferred across the LAN, WAN, or SAN from the primary site secondary storage to a NetBackup media server and then to the catastrophe recovery site storage medium (i.e., another appliance of the identical nature or tape media). With OST, the OST-enabled device is doing the replication and the data path does not comprise NetBackup media servers. This means that only changed segments are replicated, creating savings in bandwidth and, importantly, time. NetBackup is vigilant of totality copies and those copies supervene established retention policies.

Symantec Technology Enabled Program (STEP) partners -- such as Data Domain, EMC Corp., FalconStor Software, and Quantum Corp. -- leverage the NetBackup OpenStorage technology API to create plug-ins for their storage systems. OST allows for backup data to live stored on disk with whatever protocol the target device uses, such as a Fibre Channel or TCP/IP. Based on NetBackup policies or commands, the OST-enabled device will create, duplicate or delete copies.

One of the more inspiring byproducts of the utilize of the NetBackup OpenStorage interface is the performance improvement in backup. Several STEP partners with an OST-enabled solution title 50% to100% improvement in backup performance. Richard Nosal, a server administrator for high Point Regional Health System in Greensboro, N.C., implemented the NetBackup OST option with a Data Domain DD660 and saw his pre-OST 10-hour backup window with a virtual tape library reduce in half.

Since the NetBackup catalog is vigilant of totality copies, recovery of data from a NetBackup OpenStorage-optimized duplicate copy is the identical as recovery from another duplicate. Through NetBackup's Backup-Archive-Restore GUI, the OST-optimized duplicate copy can live designated as the primary copy and then a complete or granular recovery can live initiated. The potential time savings over recovery from a non-OST-optimized duplicate could live significant.

A number of options are available for providing high availability protection for applications running in the Azure cloud. Some of these options are cloud-based services. Some are in the operating system or application software. And some are purpose-built by third-parties. The numerous permutations and combinations available can execute it extraordinarily difficult to pick the best and most cost-effective solution for each application.

In general, failover clusters are the best option for assuring high availability. Historically, failover clusters were relatively simple to configure and test in the enterprise datacenter using shared storage and yardstick features built into Windows Server. But in the Azure and other public clouds, there is no shared storage. This creates a necessity to find other options for running mission-critical applications in a public or hybrid cloud environment. This article examines the options available for providing high availability (HA) for applications running within the Azure cloud. Special accent is given to SQL Server as a particularly favorite application for Azure.

Options within the Azure Cloud

The Azure cloud offers redundancy within datacenters, within regions and across multiple regions. Within datacenters, redundancy is provided by Availability Sets that dole servers across different failing Domains in different racks to protect against failures at the rack level. Availability Sets afford redundancy for some hardware failures, but provide no redundancy for a datacenter-wide failure, such as the one that occurred in Azure’s South Central US Region in September 2018. Azure offers a 99.95 percent Service level Agreement for Availability Sets, but the SLA defines downtime as when no server in the Availability Set has external connectivity.

For protection from sole datacenter-wide failures, Azure is rolling out Availability Zones (AZs). Regions that advocate AZs luxuriate in at least three datacenters that are networked with sufficiently high bandwidth and low latency to accommodate synchronous replication. Azure provides a 99.99 percent SLA for configurations using AZs, but again, the SLA only guarantees that at least one server will luxuriate in external connectivity.

To protect against major disasters, Azure offers Region Pairs, where every region gets paired with another within the identical geography, such as the US, Europe or Asia. The pairs are separated by at least 300 miles and are strategically chosen to enable rapid recovery during widespread network or power outages, or major natural disasters. Pairing too enables Microsoft to achieve planned maintenance with minimal downtime .

While Azure certainly offers the infrastructure needed to deliver high service levels, it is incumbent upon the customer to leverage that infrastructure to ensure high availability at the application level.

Options in Windows Server and SQL Server

Windows Server Failover Clustering (WSFC) comes yardstick in the operating system. For this reason, many applications leverage this proven and powerful feature in high availability configurations in enterprise datacenters. But WSFC requires shared storage, and with no shared storage available in the Azure cloud, additional provisions are needed.

In the Datacenter edition of Windows Server 2016, Microsoft addressed this problem with the introduction of Storage Spaces Direct (S2D), which is software-defined storage that creates a virtual storage locality network using locally-attached storage. S2D requires that the servers reside within a sole datacenter, however, making it incompatible with Availability Zones. This makes S2D a viable selection only for a single-site HA configuration. More robust, multi-site HA/DR protection will require the utilize more elastic data replication and HA solutions.

Like many commercial and open source software offerings, SQL Server has two of its own HA/DR features: Failover Cluster Instances and Always On Availability Groups. The utilize of FCIs (available since SQL Server 7) affords two major advantages: it is available in SQL Server yardstick Edition; and it protects the entire SQL Server instance, including system databases. A major detriment has been its necessity for cluster-aware shared storage, but that changed in SQL Server 2016 with its advocate for S2D.

Always On Availability Groups is SQL Server’s most capable offering for both HA and DR. This option can deliver a recovery time of 5-10 seconds and a recovery point of seconds or less. It too offers readable secondaries for querying the databases (with preempt licensing), and places no restrictions on the size of the database or the number of secondary instances. Among its disadvantages are the necessity to license the more expensive Enterprise Edition, which is cost-prohibitive for many applications, and its lack of protection for the entire SQL instance.

A notable detriment with totality application-specific options is the necessity for administrators to implement different HA and DR provisions for different applications. The utilize of multiple HA/DR solutions can substantially enlarge complexity and costs (for licensing, training, implementation and ongoing operations), making this another judgement why organizations increasingly prefer using application-agnostic third-party solutions.

Third-party Failover Clustering Software

With its application- and platform-agnostic design, purpose-built failover clustering software can provide a complete HA/DR solution for virtually totality Windows and Linux applications in private, public and hybrid cloud environments.

Being application-agnostic eliminates the necessity to luxuriate in different HA/DR provisions for different applications. Being platform-agnostic makes it feasible to leverage, while not depending on, various capabilities and services in the Azure cloud.

These complete solutions include, at a minimum, real-time data replication, continuous monitoring capable of detecting failures at the application level, and configurable policies for failover and failback. Most failover clusters are able to fullfil mission-critical recovery time and recovery point objectives, and most too present a variety of value-added capabilities.

Here is a comparison of three HA/DR configurations commonly used in the Azure cloud.

Clustering with Confidence

All of these options, whether implemented individually or in various combinations, can luxuriate in a role to play in making HA and DR protections more efficient and affordable for the complete spectrum of enterprise applications -- from those able to tolerate some data loss and downtime, to those that exact five-9’s of uptime with minimal or no data loss. Just live confident that the option(s) you pick provide protection at the application level for totality foreseeable failure scenarios.
